How to evaluate a Forge choice
- Confirm the fire mode. A charge, Weakspot or Secondary trigger is not valuable if the selected mode rarely produces it.
- Estimate real uptime. Distance, uninterrupted firing and kill conditions should be judged in the encounter that is ending the run.
- Repair the bottleneck. Range, magazine, reload or control can beat another damage clause if it lets you complete the attack cycle safely.
- Check interaction wording. Treat “Primary”, “Secondary”, “Weakspot” and status requirements literally; do not assume an effect applies to every source.
